A DVD-Audio disc uses 96 KHz sampling at a 24-bit depth for 6 channels (full surround 5.1).

What is the bit rate for this disc?

How much storage space will be required for 1 hour?

Bit rate = frequency * bit depth * no. of channels

=96000 * 24 * 6 = 13824 kbps

storage space required per second = 13824 Kb

Storage space required per hour = 13824 * 60*60

= 49766.4 Mb.

Explanation:

You need to understand the sampling rate first. Its the number of samples captured per second. The bit depth is the number of bits per sample. and the no. of channels is like 6 for 5.1 channels. The dolby digital is an example of 5.1 channel sound surround system and is quite extensively used to create the home theater. You fix the speakers to left, right, front back and so as mentioned. the sixth channel is for the sub woofer. Hence, the above formula.
